DATA SHEET Product description SINTOGUM Series prefabricated waterproofing membranes are produced by co-extruding a bitumen-polymer based elastomeric compound with a reinforcing mat consisting of non-woven stabilized polyester for SINTOGUM PE versions, and of reinforced glass tissue for SINTOGUM W versions. SINTOGUM Series membranes are available in 3 and 4 mm thick versions with a talc-treated upper face, or with the upper face surfaced with slate chippings in three grades: 3.5, 4 and 4.5 kg/m2. For SINTOGUM PE versions, faces may also be treated with the proprietary TEXTENE® finish, a special preformed textured polymer fiber film which enhances the product, improving durability and appearance. Specified instead of the standard talc treatment, the optional TEXTENE® finish ensures that membranes are cleaner to work with and release less dust into the environment. Membranes can also be overcoated with compatible paints. With the TEXTENE® finish, protective treatments adhere better and are more easily applied, increasing the service life of both the membrane and the protective coating. As a further benefit, paint coatings can be applied immediately after the membrane is installed, thus saving time and reducing labor costs. The lower face is coated with TERMOTENE film, which facilitates application and improves membrane adhesion to the substrate to be waterproofed. SINTOGUM Series membranes are supplied in strapped rolls, each accompanied by a Quality Control Certificate. They comply with CE marking requirements where applicable, and contain no asbestos, tar or other dangerous substances. Recommended uses SINTOGUM Series membranes are ideal for waterproofing applications of all kinds. For membrane versions to be used in roofing, foundation and below-grade applications, see the table below(1). For detailed documentation and guidance regarding product application, consult IMPER ITALIA srl Technical Services. (1) In compliance with applicable standards and AISPEC-MBP guidelines.

(SINTOGUM SERIES continued) Methods of application SINTOGUM Series membranes are designed for easy torch application, except for polyester-reinforced versions, which are secured using mechanical means. Waterproofing performance will depend to a significant extent on application methods. Substrates must be thoroughly cleaned and treated with a suitable primer applied by brush, roller or spray at a rate of 0.2 to 0.3 liters/m2. Primer coverage will depend on substrate porosity. SINTOGUM Series membranes are applied using a propane torch. Special care must be taken at joins, which must be overlapped....
